1) If the sections shown below is subjected to a negative bending moment of 10kN.m, draw the 3D bending stress distribution for your relevant section as per the colours on the class list. Please show all relevant calculations and values on your distribution. The position of the neutral axis is measured form reference point A. Problem Green 400mm 200mm 350mm 300mm 200mm 500mm 300mm A (y 294.72mm; I 8945174106.75mm) 2) Given the cross sectional area below. The horizontal neutral axis is 129.0mm from reference corner 1. The moment of inertia around this neutral axis is 1073352100.6mm*. 1 30mm 2 30mm 30mm 4 300mm -300mm F100mm- 100mm - F200mm- - 200mm 400mm 50mm a) Draw the shear stress distribution of the section if there is a shear force on the section of 10kN. b) What percentage of the shear force is carried by the cross section between 2 and 3?
